The Cultural Revolution continues to spark conflict a half-century later. Controversy erupted this weekafter a post appeared on Chinese social media suggesting that politically sensitive content about the turbulent and violent era had been removed from a middle-school history textbook. The post included photographs from the newly published edition of the required text alongside images from an older version, allegedly showing that a chapter devoted to the Cultural Revolution had been removed, a charge which the textbook’s State-run publisher has denied.
